Metabolite Identification
Common Name(E)-2-Methylglutaconic acid
Description2-Methylglutaconic acid is found in the urine of patients with organic aciduria from 2-methylacetoacetyl-CoA thiolase (EC 2.3.1.9, acetyl-CoA C-acetyltransferase) deficiency (ACAT, OMIM 607809 ). Main clinical features of ACAT include important staturo-ponderal delay, frequent infectious rhinopharyngitis episodes and an acute metabolic acidosis (this metabolic decompensation being adequately halted by bicarbonate supplementation). (PMID: 8930414 , 2925825 ).
